Blanco 443034 – Frequently Asked Questions
1) What does a dishwasher air gap actually do, and do I need one?
A dishwasher air gap breaks the siphon between the dishwasher drain hose and the sink drain, so waste water cannot get pushed back into the appliance when the sink clogs. The Blanco 443034 air gap is the fitting that sits on the deck to do that. Many plumbing codes require one on a dishwasher installation, and this one is made to satisfy those requirements.
2) Will the Blanco 443034 air gap fit a standard extra hole in my sink deck?
It is built to fit all Blanco faucet holes, so if the deck hole was drilled for a Blanco faucet or accessory it drops straight in. On a non-Blanco sink or countertop, match your existing accessory hole diameter before ordering.
3) Is the Blanco air gap plastic or metal?
Solid brass, not plastic. The PVD Steel version, part number 443034, carries a physical vapor deposition finish over that brass, which Blanco states resists tarnishing and corrosion. That matters at a sink deck where the cap sees splash and cleaners daily.
4) What finishes does the Blanco air gap come in so I can match my faucet?
Four: Polished Chrome, PVD Steel, Matte Black, and Satin Gold. Model 443034 is the PVD Steel one, which is the usual pairing with Blanco stainless and steel-finish faucets. If you are standardizing several units across a property, order the same finish code across all of them.
5) Does the Blanco 443034 air gap include the hoses to connect the dishwasher?
The 443034 is the air gap body and cap itself. The drain hose from the dishwasher and the hose running on to the disposer or drain tailpiece are sized to your under-sink layout and are bought separately, so plan on the hose run and clamps as part of the job.
6) Is this air gap for a kitchen sink or can it go on a bar or prep sink?
It is a sink-mounted accessory, and it will serve any sink deck with a spare hole and a dishwasher or similar appliance drain routed to it. The common install is a kitchen sink deck alongside the faucet.
